Three Business becomes first UK mobile network operator to launch business eSIM trial

Three Business, the business arm of Three UK, has launched the UK’s first large-scale  eSIM trial, offering over 50,000 businesses in Birmingham and Bristol a way to test its network before making the commitment to switch providers.

Switching mobile networks can be a big decision for businesses, with coverage and service quality varying significantly by location. Traditionally, businesses have relied on coverage maps, external reports, and third-party analysis to make their choice, but these tools don’t always reflect real-world conditions.

E-Sim trials are widely in use in other developed markets like the USA but this UK first trial, will allow businesses to experience the Three network first-hand for 30-days alongside their existing provider. This will allow businesses to make an informed decision based on actual performance – all through a completely smooth journey and a 100% digital end-to-end process in partnership with eSIM Go.

Snehal Bhudia, Director Three Business, said: “Choosing the right mobile network can feel overwhelming with conflicting information and the risk of getting it wrong. That’s why we’re offering businesses a free trial of our market-leading 5G network- alongside their current provider. It’s a simple, hands-on way to experience the difference for themselves, helping them make a confident, informed decision that drives real productivity gain for their business.”

The two cities were selected by Three Business due to their rapidly growing business ecosystems and status as major UK tech hubs. Birmingham is home to over 37,000 businesses[1], including leading financial services and digital firms, while Bristol is a centre for emerging tech, aerospace, and creative industries.

Ian Fogg, Research Director, CCS Insight said, “High levels of employee frustration with their current connectivity indicates the scale of the opportunity for alternative 5G solutions. The ability to easily test a different network using eSIM removes most of the risk of switching mobile operator. This is especially important for businesses because of the damage that unreliable connectivity can do to productivity.”
